Hi! I am using the Education theme and I have installed the Genesis Simple Hooks plugin. I would like to remove the date and the RSS information from the topnav section. I am unable to access my topnav.php file for a few reasons (I have multiple sites that are being managed by someone else). Anyway, this is why I installed Genesis Simple Hooks. I would like to remove the date and RSS info but I would like to keep the topnav div. In Simple Hooks under genesis_before_header Hook I added the following code:

To answer your original question, education_include_topnav isn’t a function (that I know 0f), so you’re not going to be able to remove it with Genesis Simple Hooks, and as far as I know there is no topnav.php, unless that’s a custom file that someone created, but WordPress doesn’t usually work that way so I don’t think that file exists.

I’ve recently been working with the Education theme myself, and I’m not sure why the date and RSS feed links are in that location.

Still, a simple way to remove them is to add this code to the end of your style.css file:

.topnav-left,
.topnav-right {
display: none;
}

You should be able to access and edit that file in Appearance > Editor

By the way, your site appears to be loading your Google Analytics script in two different places. You may want to remove one of those.
